Rectifier Duty Transformers are usually designed for harmonics along with additional loading and equipped with electro statistic shields that can help to prevent the transfer of harmonic frequencies in between the primary as well as the secondary windings. This type of transformer would require a specific design to be able to supply the necessary power at low voltage level. Along with the Cast Coil Transformer, these varieties of transformer are ideal for large drive applications and are sometimes called special purpose or industry transformers that have tailor made designed, ideal for high current solutions on various industry applications.

Continuous and Uninterrupted Load

Rectifier Duty Transformers are designed for continuous and uninterrupted load, making it the perfect transformer to invest for huge commercial and manufacturing industries. As you know, short time load can reduce the size of the transformer and can greatly affect the day to day operation of the company. There are often a higher number of switches on these types of transformer since they are designed mainly for several industrial applications. ...
... Furthermore, the Rectifier Duty Transformers are usually combined with a diode or a Thyristor rectifier. The applications would range from huge large aluminum electrolyses up to several medium sized operations.

Separate Voltage Regulation Unit

Just like with the Cast Coil Transformer, the Rectifier Duty is often built in or through a separate voltage regulation unit. Because of a large variety of applications available, the transformer will often have several designs up to a combination of the voltage regulation. The Rectifier Duty Transformers is also available as double stack configuration, inter-phase reactors, phase shifting, as well as transductors and filter winding. Here are the design options available for the Rectifier Duty type of transformer:

• Air cooled secondary bushing arrangement and design

• Indirect or direct regulation

• On load and off circuit tap changer

Important Role

The Cast Coil and Rectifier Duty Transformers play an important role on various industrial applications most especially when it comes to metallurgical plants and processes. As you know, very high currents are needed to supply an AC and DC electric arc furnaces. These furnaces make use of copper, aluminum, chlorine and zinc, including those in the large industrial drives. The production capacity of electricity is expected to continue to grow in a grand scale in order to meet the worldwide demand, as well as the ever increasing currents and voltages.

Severe Environment

The environment in which the transformer supply is needed can be quite severe and it is for this reason why Rectifier Duty Transformers would be an ideal choice. These transformers can be exposed to high cyclical loads as well as thermal stresses. They can also withstand frequent over currents as well as the usual over voltages in huge commercial industries. This is often due to short circuits and tripping of high voltage circuit breakers. Off the shell, the Rectifier Duty Transformers are not appropriately designed to withstand these extreme conditions. It is for this reason why they must be specifically designed in order to manage the load profile of a company and ensure an uninterrupted and reliable output.
